Synopsis for the Gulf of Mexico

.SYNOPSIS...High pressure will continue to extend from the Mid-
Atlantic states southwestward to the northern Gulf of Mexico
waters through Sunday night, as a cold front moves off the Texas
coast. Fresh to strong E winds in the NE Gulf waters will
continue for next 24 hours. Gentle SE winds in NW Gulf waters
will continue today, and then become light southerly flow just
ahead of the Sunday morning cold front for the Texas coast. The
front is expected to reach from near Apalachicola Florida to the
NW corner of the Yucatan Peninsula by Monday afternoon, from
Sarasota Florida to NW Cuba by Tuesday afternoon. Strong high
pressure will build southeastward across the area in the wake of
the front with fresh to locally strong northerly winds spreading
from W to E across the forecast waters.
